Are you saying you want the lens flare to only appear inside the logo?  I might use the Preserve Transparency layer switch for that, but the details of your comp may demand another solution.  In other cases using an Alpha Track Matte or Set Matte with a pre-comp of your logo animation would probably work.

If that's not what you're after can you please try to explain it again and spell out in detail what it is you currently have versus what you'd like to have.

Hi,

I have a logo resolve with its accompanying logotype and a light flare on add mode moving across it. Logotype fades up from 0 opacity and starts blurred, ending sharp. I want to render with an alpha channel and retain the flare effect on the logo/logotype but lose the flare from outside the object. I’m making my own luma matte and trying to matte in the flare but it seems to strangle the edges when the type is blurred. Any suggestions on the correct way to do this?

Cheers.
